SHEET-METAL WINDOW -SASH.

Specification of Letters Patent.

Patented Oct. 17, 1905.

Application filed July 14,1904. Serial No- 216,497.

To (LZZ whom it may concern:

Be it known that I, EDWARD G. BUDD, of the city and county of Philadelphia and State of Pennsylvania, have invented an Improvement in Sheet-Metal lvindowfiashes, of which the following is a specification.

My invention has reference to sheet-metal window-sash; and it consists of certain improvements which are fully set forth in the following specification and shown in the accompanying drawings, which form a part thereof.

The object of my invention is to provide a construction of sheet-metal window-sash especially adapted for railway-cars which shall embody simplicity, cheapness, rigidity, and durability.

In carrying my invention into practical form 1 construct the window-sash of sheet metal bent into tubularshape substantially rectangular in cross-section and in which the inner edges of the four bounding bars of the sash are provided with flanges, formed by one edge of the metal being bent one over the other, and combine it with the glass pane and retaining-stri iis which clamp the edges of the glass to the flange, and which retaining-strips are secured in place by screws passing through said retaining-strips and flange.

My invention also includes details of construction, which, together with the features above specified, will be better understood by reference to the drawings, in which- Figure 1 is a front elevation of a windowsash embodying my invention. Fig. 2- is a section of sash on line 2 2, and Figs. 3 and 4 are similar sectional views of modifications of same.

A is the sash-frame and is made of the four sheet-metal bars joined into a rectangular frameand ofa cross-section such as shown. These bars are each substantially rectangular in cross-section. having their edges joined in a flange, as at B, by one edge D being bent over the other edge O. I also prefer to provide the step E on the glass side of the flange of the bars upon which to seat the edge of the glass, as shown in Fig. 2. The step E thus forms a part of the flange. Spacing- .blocks J may be secured by riveting to the sheetmetal D to give rigidity under the step portion E and to provide means to receive.

the clamping-screws I.

H represents glass-retaining strips and fit against the steps and edges of the glass G and are mitered or suitably butted at the corners.

The clamping-screws I extend through the retaining-strips H and part O of the sheetmetal sash-bar and screw into the blocks J.

I do not confine myself to any manner of applying the screws, as they may be ordinary bolts, if so desired, with round nuts, as shown in Fig. 3. The glass may be bedded in the groove between the flange B and strip H with putty or cement, or may have a piece of felt, cloth, or rubber placed about its edges, as at L, to hold it firmly against rattling and without dangerof cracking. The bars of the sash may have the outer edges F beveled, as shown, and this will more readily shed the water in the case of the bottom portion of the sash. These edges may also be slightly inclined under the edges of the retaining-strips, as at F, and the lower edges of the strips made to correspond, so that they make water-tight joints when drawn up tightly into place by the clamping-screws.

To cause the glass to be nearer the center of the bars of the sash A, an oflsetK may be made in the wall of the bar by suitably bending the sheet metal. This also gives a more artistic finish on the inside of the sash.

In the construction shown in Fig. 3 the step E of the flange is of less width, and the retaining-strip H. is thickened at its lower portion in proportion. In this figure the ofiset K of Fig. 2 is omitted, which brings the glass nearer to the inner surface of the sash. The screw for clam ping the retaining-stri p H in this case is made in the form of a bolt, as before described.

In Fig. A the same general construction as in Fig. 2 is embodied; but the step E is practically omitted and the lower part of the retaining-strip I-I thickened, as at E, to support the edge of the glass and felt, putty, or other packing, such as asbestos.

WVhile I have described my invention as especially applicable to window-sash frames, it is equally applicable for all purposes where a panel is to be secured and held whether the said panel is transparent or opaque, of glass, metal, or other material, solid or otherwise, and wherel use the term panel in the claims it is to be taken with the generic meaning, ineluding glass, metal, or other material.

The essential feature of the sash is the construction of the bars thereof of sheet metal bent into rectangular tubular form with a flange at the glass or panel side, combined with the retaining-strips and clamping devices for holding them in position, and while I prefer the construction shown I do not confine myself to the details, as they may be modified in various ways without departing from the spirit of the invention. 7

Having now described myinvention, What I claim as new, and desire to secure by Letters Patent, is-

1. A metallic sash formed of a rectangular frame of sheet metal havingin wardly-directed flanges, combined with a panel of considerably less width and length than the corresponding distances across the space within the body of the frame and of greater width and length than the corresponding distances measured across the space bounded by the'inWardly-directed flanges whereby the latter extend beyond the panel, retaining-strips extending over the surface of the panel near its edge and extending to the body of the rectangular frame, and means for uniting the retainingstrips to the inwardly-directed flanges arranged beyond the panel and extending transversely thereto whereby the said retainingstrips are clamped against the panel.

2. A metallic sash formed of a rectangular frame of sheet metal having tubular sides made with lapped edges to form inwardly-directed flanges provided with laterally-extending steps to support the edges of a panel, combined with a panel, retaining-strips for the panel and means for clamping the retaining-strips to the flanges extending below the step and through the flange of the rectangular frame.

3. Ametallic sash formed of a rectangular frame ofsheet metal having inwardly-directed flanges provided with laterally extending steps to support a panel, combined with retaining-strips to clamp the panel having thickened portionsinline with the steps, and clamping means for clamping the retaining-strips to the step portions of the flanges.

4:. A metallic sash formed of a rectangular frame of sheet metal having inwardly-directed flanges provided with laterally extending steps to support a panel, reinforcing spacingblocks secured to the flanges, combined with retaining-strips to clamp the panel, and clamping-screws extending through the retainingstrips and into the spacing-blocks forclamping the retaining-strips to the step portions of the flanges.

5. The combination of the rectangular sashframe made with tubular sides of sheet metal and bent upon itself to form inwardly-directed flanges B, with a glass G of dimensions suflicient to overlap the flanges but not to reach the tubular sides of the sash-frame, soft strips L extending over and bounding the edges of the glass, retaining-strips H for clamping the edges of the glass through the soft strips, and clamping-screws extending through the retaining-strips and flange of the sash-frame beyond the edges of the glass and soft strips.

6. A sheet-metal sash consisting of a rectangular frame, the four bars of which are each composed of tubular sheet metal and having on its panel side a flange and a step portion extending laterally from the flange.

7. A sheet-metal sash consisting of a rectangular frame, the four bars of which are each composed of tubular sheet metal and having on its panel side a flange and a step portion extending laterally from the flange, and in which the sheet-metal edge extending from the step portion is secured .to the other edge to form the flange by one being bent over the other.

8. A sheet-metal sash consisting of a rectangular frame, the four bars of which are each composed of tubular sheet metal rectangular in cross-section and having on its panel side a flange and a step portion extending laterally from the flange and in which the said flange and step portions are located intermediate of the two vertical walls of the bar so as to bring the panel-supporting step portion nearer the middle of the bar transversely considered.

In testimony of which invention I hereunto set my hand.
